WILLIAM C. SPELMAN, OF NEW YORK, N. Y., ASSIGNOR TO THE NEW YORK STEELMAT COMPANY, OF SAME PLACE.

METALLIC MAT.

SPECIFICATION forming part of Letters Patent No. 438,648, dated October21, 1890.

Application filed February 18, 1890. Serial 110,340,903. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM C. SPELMAN, a citizen of the United States,residing in the city of New York, county, and State of New York, haveinvented a certain new and useful Improvement in Metallic Mats, of whichthe following is a specification.

'My invention relates to that class of cellular mats kn own as metallicor Rochester mats, and has for its object the insertion of pieces ofrubber in the cells of said mat or around the edge or edges, whereby theshoes .may be additionally cleaned after being scraped upon the metallicsurface of the mat.

x 5 My invention is illustrated in the accompanying drawings, which formpart of the specification, in which- Figure 1 is a plan view of myimproved mat; Fig. 2, a cross-section of the same, taken 2: through theline 0 c, Fig. 1; Fig. 3, a detail View of my improved mat, showing therubber border inserted at one end of the mat; Fig. 4, a cross-section ofthe same, through the line k is, Fig. 3. Fig. 5 is a detail view of myimproved mat, showing the rubber border inserted at both ends of themat. Fig. 6 is a cross-section on the line 0 c, Fig. 3; Fig. 7, across-section on the line k is, Fig. 3. Fig. 8 is a view of a detachableframe, which may be used to secure the rubber border between thecorrugated or scraping surface of the mat and the binding-edge. Fig. 9is a cross-section of a single block of rubber, which illustrates oneform of accomplishing my invention; Fig. 10, a perspective View of thesame, and Fig. 11, a longitudinal section of a series of these singleblocks placed in position to form the border.

Similar letters throughout the several views indicate similar parts.

A represents the metallic strips composing the cellular or scrapingsurface of the mat; B, the metallic rim surrounding the mat.

D D are rods running across the mat, se-

5 curing the scraping-strips to the rim B.

E is the rubber filling, which maybe a continuous band of rubber, asshown in Fig. 1, out half through at certain points to render it moreflexible and to adapt it to be inserted in cells of the mat and to beretained therein; or else the filling may be of single blocks, as

shown in Figs. 9, 10, and 11, which are grooved at the edges to receiveand conceal between them the metal bars of the mat proper that hold saidblocks in place, as in Fig. 11.

G is a frame or partition of metal, with projecting arms G, which may beplaced along the sides of the mat within the rim and held in position bythe cells of the mat and by riveting the arms G G to the rim B. Thisframe or partition forms recesses, into which the rubber filling may beplaced.

The ordinary Rochester or metallic mat, as shown in Patents Nos. 377,580and 387,978, is composed of a number of metallic strips corrugated or oherwise formed to present a cellular appearance, and these strips arefastened or secured to the rim B by the transverse rods or bars D D,passing through the strips and riveted to the said rim.

In my improved mat I insert in the cells of the mat, by preference nearthe rim B, blocks of rubber, thus forming a combined scraping andelastic surface.

The advantage of thus having a rubber filling in the mat is that thesurplus dirt which remains on the feet after being scraped on themetallic strips will be removed by the rubber, as willalso moisture andslush should the day be rainy.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination, in a metallic mat hav ing an outer continuous rim Band metallic strips or filling A, of a separate inner partition G,furnished with projecting arms G, and of the filling-blocks E ofindia-rubber, inclosing said arms G and presenting an even surface tothe foot, substantially as and for the purposes set forth.

2. The combination, with a metallic mat consisting of a continuous outerrim and innor filling A, of a partition G, having projecting armssecured to the rim of the mat and inclosed within the rubber blocks E,the said partition G resting against the filling A, as

and for the purposes specified.
